tandard form equation for a circle with center (h,k) and radius r is: (x−h)2+(y−k)2=r2 So you have the center, now you just need the radius. Well, given the center and a point on the circle, the radius is just the distance between those 2 points. so use the distance formula to find the distance between those 2 points, which is your r: d=(x1−x2)2+(y1−y2)2−−−−−−−−−−−−−−−−−−√ Then plug your center point coordinates, and your r, back into the circle equation that I gave you abo
